Computer Aided Quality Assurance Systems
Quality has always been a major human concern and so has been the need to measure quality. Ever since the introduction of the concept of mass production, quality control has grown into an important field and has made rapid progress in technology and its application.
Traditionally quality control function is performed by a team of inspectors using conventional tools and sampling plans with the sole aim of stopping a defective item passing through the inspection stage. This process, though designed to be foolproof, lacks in implementation due to the sheer volume of work involved and dependence on human judgement at each stage. Factors such as fatigue, perception, bias etc. affect the overall outcome of this system.
Introduction of computers, tend to eliminate some of these problems, especially consistancy of judgement, and in addition provides quick storage, retrieval and analysis much needed for decision making at all levels.
This paper brings out benefits achieved by introduction of computer aided QA systems in a light engineering plant engaged in manufacture of precision engineering components and products.
